To all whom it may concern.'

Be it known that I, MARTIN W. PARELIUS, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and Improved Collapsible Table, of which the following is a specification.

Myl invention has reference to that class of collapsible or oldable tables adapted for picnic and other like duting purposes; and as a mess table forI armies, etc., and it primarily has for its purpose to provii atable of the general character stated, the several parts of which may be readily folded together in a compact and a comparatively small spacevfor packing and transportation and which, when set up for use, is strong and rigid v Another object of my invention is to provide a table consisting of a supporting pedestal or stand and a roll top removably mounted onethe said stand, the latter being and number of parts, the parts being also correlatively so arranged that the top may be instantly detached from the stand and rolled up, and the stand folded latWise into such a compact body, whereby it can be readily slipped within the rolled up top and the whole assembled to be `conveniently stored or transported.A

Another object of my present invention is to provide, in an improved table structure of the character stated, two end and two side elements, each composed of two cross ,diagonal centrally pivoted legs with the` respective adjacent lower ends of the several sets of side and end elements pivotally 4joined in such manner that the spreading or contracting of one ormore o'f the said elements effects the spreading 'and contracting of the entire-supporting structure which, when at the limit of its folded or contracted condition, forms a substantially compact elongated body.

Again, my invention seeks to p provide a table structure comprising an improved collapsible supporting frame,

top supportin bars, coperating elements on the bar an the upper corners -of the supporting frame pporting are so arranged that thev su bars can be placed in their voperatlve posi,- tion when the supporting frame Iis partly extended and the 'said bars relatively so mounted with respect to the supporting .cated as near the final closure frame that the application of a downward i pressure on the said bars tends to extend the supporting framen to the limit and automatically efects the interlocking of the bars and the supporting frame,'whereby to hold the said frame rigid and in condition for receiving the top upon the supporting bars, the latter and the top havin-g interlocking means. p

Furthermore, my invention seeks to provide in a table construction of the kind stated, an expansible and contractible supporting frame, top .supporting bars adapted for engagingthe opposite side or end meI nbers of the supporting frame, the top corners of the said supporting frame having' locking brackets for receiving the said bars and the said bars have locking elements adapted for automatically moving into an interlocked engagement Awith the said bracket, when pressure is applied upon the 'bars for extending the supportingframe to become automatically interlocked from the said bracket as pressure is applied to fold up or contract the said supporting frame.

With other objects in` view that will here# inafter appear, my invention provides an improved construction of table of the general type stated, including the details of stru-cture and the peculiar combination of parts fully explained in the following description,

specifically pointed out inthe 'appended' said frame are adapted for being adjusted totheir final or interlocking position;

Fig. 3 is a perspective view which shows the supporting frame, the parts being indior` folded posit1on.

Fig. 5 is a detail transverse section of one of the table top supporting bars, a portion of the roll top locked thereon, an adjacent corner portion of the supporting fraine and a bar and frame interlocking device.

Fig. 6 is a perspective view of one end of the supporting frame, the parts being atv ,their final folded up position, the manner in which tlietable top supporting bars are assembled therewith being indicated in dotted lines.

Fig. 7 is a perspective view that shows the folded up Vtable packed in a tubular-sliaped receptacle.

Fig. 8 is a cross section on the line 8 8 on Fig. 7. Y

In carrying out my invention, I provide a supporting structure in the nature of a frame foi-ined of four pairs of cross legs,

designated 1 2 3 ;l. each pair being united by a. central pivot designated 10-20- 30-4-0.

The lower ends of each pair of legs are l Y iiexibly joined wit-h the coincident ends of ets 11 to corner plates 6, preferably of heavy galvanized iron bent into right angled shape to constitute front and side faces to which the said upper ends of the .respective front and side leg members are connected, as is -clearly shown i'n Fig. l which also shows the upper edge of the angled faces of the plate formed with a pair of notched seats 61-62 disposed at right angle to each other, the ends of Awhich terininate at vertical extensions (i3-6l whose edges, that face the seats 61 62, are formed with horizontal locking slots 65 65, the purpose of which will presently appear.

By constructing the legs that constitute the frame, of four sides, each consisting of a pair of cross leg members yand providing the said Vcross leg members with specially arranged corner connections that jointhe upper'and lower adjacent leg ends as stated and shown, the framing can be quickly folded up in a very compact shape, as indicated by Fig. ,3, which shows the frame as closed nearly to its limit. Figs. 6, 7 and`8` -shoW the parts that constitute the framing,

adjusted to the completely closed condition, it being apparent that, when folded to the said condition, as indicated in Fig. 6, a central opening square in cross section, eX-

tends the full length of the foldedup frame.

Coperating with the folda'ble frame 1s a pair of top supporting bars 7 7, each of which, at eac-h end, has a dovvel pin and an adjacent aperture-71, the said p ins and apertures on the two bars providing for locking said bars flatwise onto each other to permit of sliding them into the central opening :c of the closed up framing, as is indicated in dotted lines in Fig. 6V Vand as is shown in full lines inthe horizontal section Fig. 8.

nach bar t is of Such width am, whey placed in operative connection with the ex the notches 65 of the member 63 engage, when the table frame is bodily extended, it

being obvious from Fig. 2 that, When the bars 7 7 are placed on the cornerbrackets 6--6 in the manner indicated, .that any downward pressure applied to the said bars 7 7 causes the leg portion tospread until the screw studs 8 engage and interlock with the notches 65. of the corner or bracket meinbers 63. l

The table top 9, in my construction of table, is composed of an apron of slats 90 flexibly connected, preferably by wire 91,

Vthreaded through theA several slats.

In putting the top in position, the apron of slats is unrolled and disposed flatwise onv the bars 7 7. The opposite end slats have apertures 92 92 that interlock with the studs 7 0 70 on the. bars7-7, as indicated by the dotted arrows y/ yon Fig. l. K

vI" rom the foregoing description taken in connection with the drawings, the complete construction, the manner of setting up my table and folding the parts so thatthe supporting frame and the top bars may be readily closed up into compact form for rolling the slatted apron table top around the said folded frame" structure, will be readily apparent.

One of the advantages in forming the parts thatconstitutemy table structure as I stated and shown, is that they maybe quickly folded up and the folded pack can be quickly vinserted into a tubular receptacle, see Figs. 7 and 8, for shi ping and storing.

My construction of tal le is simple and the parts are individually so designed that they may be produced at a practical nominal cost, to thereby provide for the production of a table of the character stated of a strong and durable nature and at a relatively small expense.
